| 中文摘要 |
| 采用 4种活性炭纤维 (ACF)作为吸附剂 ,对水中 CHCl3、CCl4、高锰酸钾指数 CODMn、紫外吸光值 EUV254等有机微污染物的去除进行了初步研究 ,并与 ZJ-15型颗粒活性炭 (GAC)进行了对比 .吸附等温线的结果表明 ,ACF3对 CHCl3的去除效果最好 ,当 CHCl3的平衡浓度为 60μg· L-1 时 ,ACF3对 CHCl3的吸附容量为 212μg·g-1 ;GAC对 CCl4的去除效果最好 ,当 CCl4的平衡浓度为 3μg· L-1时 ,GAC对 CCl4的吸附容量为 0.83μg·g-1;GAC及 ACF1对 CODMn、EUV254有较好的去除效果 ,当CODMn的平衡浓度为 2.5mg·L-1 时 ,GAC及 ACF1对 CODMn的吸附容量分别为 2.16mg·g-1 和 1.98mg·g-1 ,当 EUV254的平衡浓度为 0.05时 ,GAC及 ACF1对 EUV254的吸附容量分别为 0.32 g-1和 0.15g-1. |
| 英文摘要 |
| The removal of micropollutants in water such as CHCl3,CCl4,CODMn and EUV254 by four type of activated carbon fiber(ACF)was studied in the paper and also compared with ZJ 15 type GAC.Absorption isotherm results show that good removal efficiency of CHCl3 can be obtained by ACF3 and its absorption capacity is 212μg·g-1 when the equilibrium concentration of CHCl3 is 60μg·L-1 .Good removal efficiency of CCl4 can be obtained by GAC and its absorption capacity is 0.83μg·g-1 when the equilibrium concentration of CCl4 is 3μg·L-1.Good removal efficiency of COD Mn and EUV254 can be obtained by GAC and ACF1.The absorption capacity of GAC and ACF1 for CODMn is 2.16mg·g-1 and 1.98mg·g-1 respectively when the equilibrium concentration of CODMn is 2.5mg·L-1 and for EUV254 is 0.32 g-1 and 0.15 g-1 respectively when the equilibrium concentration of EUV254 is 0.05 |
